Subject: [PATCH 07/11] remoteproc: imx_dsp_rproc: Move imx_dsp_rproc_dcfg
 closer to imx_dsp_rproc_of_match

Move the imx_dsp_rproc_dcfg structure definitions closer to
imx_dsp_rproc_of_match to prepare for adding start/stop/detect_mode ops for
each i.MX variant.

Avoids the need to declare function prototypes such as
'static int imx_dsp_rproc_mbox_init(struct imx_dsp_rproc *priv)' at the
beginning of the file, improving code organization and readability.

No functional changes.
